Une construction intrinsèque du cœur de l'invariant de Casson  [ An intrinsic construction of the core of Casson's invariant ]
Annales de l'Institut Fourier, Volume 51 (2001) no. 6, p. 1741-1761

We give a new cohomological construction of the core of Casson's invariant and give a new computation of its values on the generators of the Johnson subgroup of the mapping class group.

Nous donnons une nouvelle construction cohomologique du cœur de l'invariant de Casson et nous donnons un nouveau calcul de ses valeurs sur les générateurs du sous- groupe de Johnson du mapping class group.
